Problems solved by technology

[0004] The spray-bonded cotton and silk-like cotton currently on the market are mainly made of coarse denier polyester ordinary staple fibers (such as 2.2dtex, 3.3dtex, 5.5dtex polyester ordinary staple fibers) and three-dimensional crimped fibers (such as 6.7dtex, 7.8dtex) Three-dimensional curly fiber), although its bulkiness and resilience are better, but the space between the fibers is relatively large.

Example Embodiment

[0031] Example 1

[0032] First, by weight, equipped with the following raw materials: 40% ultra-fine denier fibers (all ultra-fine denier polyester fibers, with a fiber fineness of 0.78 dtex and a length of 51 mm), and 38% fine denier fibers (all fine denier fibers) Polyester fiber, the fiber fineness is 1.32dtex, the length is 51mm), the bonding fiber is 20% (all are polypropylene polyester composite fibers, the fiber fineness is 4.4dtex, the length is 51mm), the binder is 2% .

[0033] Then, follow the steps below to make warm batts (reference figure 1 ):

[0034] (1) Open and mix fiber materials such as superfine fibers, fine fibers and bonding fibers;

[0035] (2) Carding and spreading the mixed fiber materials to form a fiber web; the carding equipment used adopts single cylinder and double doffer, and the card clothing adopts an ultra-fine tooth structure (the tooth spacing of the card clothing is 1.8mm) ;

[0036] (3) Carry out the second carding and web laying; the structure...

Abstract

The invention relates to insulation flocculus which is made by 20-80 percent by weight of superfine denier fiber, 10-70 percent by weight of fine denier fiber, 5-30 wt% of tacky fiber and 0-5 wt% of bond. The insulation flocculus is made by adopting the following steps of: loosening and mixing the fiber raw materials; carding and lapping to form a fiber web; carrying out disorder traction on the fiber web to enable the fiber web to form a solid meshy across structure; spraying the bond on the two faces of the fiber web; heating and baking the fiber web to enable the tacky fiber to bond the fiber around and to solidify the bond. In the invention, due to the adoption of the superfine denier fiber and the fine denier fiber, heat conduction can be effectively reduced, cross ventilation in the space can be prevented or reduced, and the insulation property of the insulation flocculus is improved. In addition, due to the adoption of the tacky fiber and the bond, the fill power and the compression resilience of the insulation flocculus can be improved, and the fill power and the compression resilience of the insulation flocculus are higher through disorder traction.

Description

technical field [0001] The invention relates to a heat-preserving wadding made of superfine fibers and a manufacturing method of the heat-preserving wadding. Background technique [0002] Warm flakes are the main accessories of clothing, mainly to prevent cold and keep warm, and their texture is usually relatively soft. The materials used in traditional thermal insulation sheets include natural thermal insulation materials such as cotton wool, cashmere and down. Among these natural thermal insulation materials, down is the best thermal insulation material, followed by cashmere, and then wool. Medium warmth is the worst. Most natural thermal insulation materials have a high moisture absorption rate and poor resilience. After a period of use, the thermal insulation performance of thermal insulation wadding will be greatly reduced. Therefore, natural thermal insulation materials are constantly being eliminated during the development of thermal insulation wadding. Among natura...
